using two loops. The inner loop is executed to provide approximately 100ms delay and is repeated 10 times, using outer loop to provide a total delay of 1 second.

What is null loop example?

Here is an example of a null loop for (x=0; x<500000; x++). Notice that in this example, a semicolon is placed directly after the closing parenthesis of the for loop. Putting the semicolon directly after the for loop (and using no braces) creates a null loop—literally, a loop that contains no programming statements.

What is the similarity and difference between for and while loop?

For loop While loop
Once the statement(s) is executed then after increment is done. Increment can be done before or after the execution of the statement(s).
